Blake Shelton says he's thankful for new girlfriend Gwen Stefani after reportedly spending Thanksgiving apart.

Speaking with "Entertainment Tonight" ahead of Monday night's episode of "The Voice," the freshly divorced country star said he's grateful for Stefani for "tons of reasons," but added he's mostly appreciative of how "she makes us all look a whole lot better on this show."

Shelton, 39, also gushed over Stefani's imminent performance of her single "Used To Love You," saying her dress for the show is "stunning."

After their respective Thanksgiving festivities, Stefani, 46, was spotted driving with Shelton in Los Angeles Sunday. Sources tell E! News the couple are "extremely happy" after making their relationship public.

Stefani split from longtime husband, Bush frontman Gavin Rossdale, in August.

Speaking with Ryan Seacrest in early November, the No Doubt singer said her life "blew up" in her face at the time, and her divorce was "abrupt."

"What I will tell you is that I was married for a long time and now I'm not, and it's a shock," she said.

Shelton officially split from his wife of four years, Miranda Lambert, in July. In a joint statement at the time, the two expressed their disappointment in the split, but said they are moving forward "separately."
